CINCINNATI — Military and history buffs will be able to watch online as surviving Doolittle Raiders make a final toast Saturday to comrades who died in or since their World War II bombing attack on Japan.

The Air Force plans to live-stream the annual ceremony — on http://www.nationalmuseum.af.mil — from the National Museum of the U.S. Air Force near Dayton starting at 3 p.m. PST.

There will also be news media coverage of what traditionally has been a private gathering.

Public events ahead of the invitation-only ceremony include a gathering to greet the Raiders as they arrive, a memorial service, a B-25 bomber flyover and movies such as the “Thirty Seconds Over Tokyo” depiction of the 1942 mission. Only four of the 80 Raiders are still alive, and one isn't able to travel.

For decades, the Raiders have offered a toast “to those who have gone” with specially engraved silver goblets at their annual reunions.

After Maj. Thomas Griffin of Cincinnati died in February at age 96, the survivors decided that this year's annual April reunion would be the last and that they would gather for one last toast the weekend before Veterans Day.

“I'm looking forward to it,” said David Thatcher, 92, of Missoula, Mont. His wife, children and other relatives will accompany him, he said by telephone this week.

He said he can't predict the emotions he'll feel at the toast ceremony.

“I don't have any idea what it will be like until we're there,” said Thatcher, an engineer-gunner on the mission.

The toast grew from reunions led by Lt. Col. James “Jimmy” Doolittle, who commanded the daring mission credited with boosting American morale and shaking the Japanese after a string of military successes.

Lt. Col. Robert Hite of Nashville, Tenn., 93, who was captured by the Japanese after the attack, won't be able to attend because of health problems but hopes to watch at home, a museum spokesman said.

The goblets, presented to the Raiders in 1959 by the city of Tucson, Ariz., have the Raiders' names engraved twice, the second upside-down. During the ceremony, white-gloved cadets pour cognac into the participants' goblets.
